The GNU shtool program is a compilation of small but very stable and
portable shell scripts into a single shell tool. All ingredients
were in successful use over many years in various free software
projects. The compiled shtool program is intended to be used inside
the source tree of free software packages. There it can take over
various (usually non-portable) tasks related to the building and
installation of such packages.
